All for One

Name: All for One Age: 121+, looks 40. Height: 7'4 Appearance: After being mortally injured by All Might years ago, All For One's face was entirely made up of scar tissue, extending from above his upper lip and covering his entire head and the back of his neck. As such, he had no visible nose, ears, hair, or eyes, though the outlines of his eye sockets were visible. All For One was blind but used an Infrared Quirk to "see," and he would sense the directions of vibrations in the area around him, similar to echolocation. There was a small hole in each palm of his hands, which is how he stole and transferred Quirks. In the past, All For One was a towering man with a powerfully muscular physique, imposing features, short white hair, and faded red eyes that showed no sense of feeling. He usually wore a dark suit over a white shirt. When All For One left his secret hideout during the Kamino Incident, he donned a navy blue, skull-like gas mask with angular tubes at the top, a wide collar-like life-support system around his neck with additional pipes connecting in the front and back, presumably to help him breathe. Personality: All For One was a subtle, sadistic, and malevolent man who liked to rule from the shadows and enjoyed himself at the expense of people before discarding them. In the past, All For One used his power to help people, but in exchange for their servitude. Once they could no longer follow his orders, All For One would callously abandon them, and his followers purged those who defied his will. Taking advantage of the chaotic era caused by the uprising of Quirks, All For One offered people anything they wanted as long as they followed him, including choice and power to those who had none, where he would take Quirks from those who didn't want them and gave Quirks to those who wished for strength, all as a means to gather numbers and conduct his schemes through other people. He masked his true intentions by claiming that he just wanted to help restore order and balance to society. All For One exhibited extreme megalomania and even traits of an outright God complex, having compared himself to the Demon Lord he read about in comic books. He also relished his total power over Japan and saw himself as a higher being. All For One would steal the most powerful Quirks during his rise to power and crushed anyone who stood in his way. He also displayed signs of kleptomania, claiming that he couldn't resist stealing a powerful Quirk when the opportunity presented itself. Quirk: All For One (オール・フォー・ワン Ōru Fō Wan?): All For One's Quirk allows him to steal other people's Quirks, leaving them Quirkless, and wield the Quirks as his own. All For One can also redistribute his stolen Quirks to other people.

His multiple Quirks grant him a very wide variety of options in combat, and he can combine his stolen Quirks to create compound attacks with devastating effects. However, he cannot steal the original users' Quirk proficiency and is therefore limited by his own skill with his stolen powers. Because of this, he prefers to steal Quirks that rely more on raw power, rather than ones that take practice and experience to master. In order to steal a Quirk, he also must physically touch the user's body, as touching something produced by a Quirk, such as the flames of a fire user, would not suffice.

While he can steal any Quirk, All For One's body cannot properly contain Quirks of newer generations, which is the reason why he sought Dr. Garaki's medical research. He also mentions having frequent nightmares where the consciousnesses of the people he stole Quirks from appear before him. To top it off, All For One's permanently injured body puts a limit on how many Quirks he can take and use in succession, making him far weaker than he was in his prime.
